29 hours of Ha, OIII and SII in subs of both 600s (for the outer shell) and 60s (for the core), combined into one image. The insert shows the upsampled core with way more detail than I would have expected from my modest 115mm f/5.6 refractor. Taken from my city balcony in Munich with an ASI183MM mono camera and Antlia 3nm narrowband filters. I hope yo like it!

And I shot the subs over the last year - the nebula being close to the north celestial pole means I can always fit in an hour or two for this object when other ones are getting too low

True

considering the fact you made 2 different subs, how did they not overlap each other? 600s for the outer shell would literally overexpose the core, how is this pulled off

I used the Substitute script for Pixinsight to replace the core. See here: https://youtu.be/WWpAQThKOPI
